Definitions

  • the present disclosure relates generally to fluid regulators and, more particularly, to two-piece trim for use with fluid regulators.
  • Fluid valves and regulators are commonly distributed throughout process control systems to control the flow rates and/or pressures of various fluids (e.g., liquids, gasses, etc.).
  • fluid regulators are typically used to regulate the pressure of a fluid to a substantially constant value.
  • a fluid regulator has an inlet that typically receives a supply fluid at a relatively high pressure and provides a relatively lower and substantially constant pressure at an outlet.
  • a gas regulator associated with a piece of equipment e.g., a boiler
  • Fluid regulators typically control the flow and pressure of fluid using a diaphragm having a set or control pressure force applied to one of its sides via a bias spring.
  • the diaphragm is also coupled directly or via a linkage (e.g.. a lever) to a valve plug that is moved relative to an orifice of a seat ring that fluidly couples the inlet of the regulator to its outlet.
  • the diaphragm moves the plug in response to a difference between the outlet pressure and the set or control pressure to vary the flow restriction provided by the plug to achieve a substantially constant outlet pressure, which provides a balancing force to the other side of the diaphragm that is equal or proportional to the set or control pressure.
  • trim including a cage that interposes in the flow path between the inlet and outlet of the fluid regulator to provide certain fluid flow characteristics.
  • some cages may be designed to provide torturous or other types of flow paths to reduce noise associated with flowing fluid.
  • noise reduction cages commonly referred to as sound trim
  • Other regulator trim designs provide cages that provide certain fluid flow or regulation characteristics to suit the needs of a particular control application.
  • the cages may be configured to provide particular, desirable fluid flow versus pressure drop characteristics.
  • regulator trim designs may also provide different types of seats or seat rings.
  • the size of the orifice may be varied to provide a more restricted seat (i.e., a seat that provides a relatively higher pressure drop at any given fluid flow rate) or a less restricted seat (i.e., a seat that provides a relatively lower pressure drop at any given flow rate).
  • known regulator trim utilizing a cage typically provides the cage and seat ring as a unitary or one-piece structure.
  • a unitary or one-piece trim configuration eliminates the possibility of tolerance stack up that could occur if multiple components were used.
  • the alignment of the cage and/or seat with the regulator body could be compromised by the cumulative tolerances of multiple, separate trim components.
  • known unitary or one-piece trim enables the regulator to be used in certain vertical applications (e.g., where the bonnet is vertically oriented and pointing downward. In such vertical applications, if the regulator trim is to be serviced (e.g., replaced), installation of replacement trim would be very difficult, if not impossible, if the trim were not of a unitary or one-piece construction.
  • the installation e.g., stacking
  • multiple trim components would likely result in a first installed component falling out of a desired mounting position and/or the regulator body (i.e., falling downward) while a second component is installed on top of the first component.
  • Yet another known regulator trim configuration provides only a seat ring (i.e., a seat ring without an integral cage), which is held in place within the regulator by pins.
  • a seat ring i.e., a seat ring without an integral cage
  • One such known configuration may be found in the EZH and EZL regulator products manufactured by Fisher Controls International LLC.
  • the present invention relates to a trim assembly according to independent claim 1.
  • the example fluid regulator trim described herein provides a two-piece regulator trim configuration that enables interchangeability between multiple types of seat rings and cages. As a result of the interchangeability provided by the two-piece trim described herein, fewer total components are needed to provide a greater variety of trim configurations for fluid regulators. In other words, with the example fluid regulator trim described herein it is not necessary to manufacture and inventory each possible combination of seat configuration and cage configuration as is typically required with known unitary or one-piece trim designs. Instead, only the interchangeable seat ring and cage components need to be manufactured and stocked and the various different combinations of these components can be made as needed to suit particular applications.
  • the example two-piece fluid regulator trim described herein includes a cage and seat ring that can be removably coupled together.
  • the example seat rings described herein include a stepped profile having a first or outer shoulder that receives the cage.
  • the example seat rings include a second or inner shoulder between the first shoulder and a sealing surface adjacent an orifice of the seat ring.
  • the second shoulder is at a different height than the first shoulder, thereby forming a circumferential step or wall on the seat rings that facilitates the precise alignment of the cages and seat rings.
  • the stepped configuration of the example seat rings described herein substantially minimizes or eliminates the manner in which the tolerances of these individual components could adversely affect (e.g., as a result of tolerance stack up) the operation of a fluid regulator.
  • example seat rings and cages described herein can be removably coupled in a manner that facilitates field service (e.g., replacement, repair, etc.) of the regulator trim, particularly in vertical applications (e.g., where the regulator bonnet or upper actuator casing is oriented downwardly). More specifically, the example seat rings and cages may be removably coupled (e.g., removably held together) using a grease (e.g., applied to the first shoulder), an interference fit, threads, etc. to prevent the cage and seat ring from separating and falling out of the regulator during replacement or repair operations.
  • a grease e.g., applied to the first shoulder
  • the fluid regulator 100 includes an actuator 102 that is operatively coupled to a valve 104.
  • the actuator 102 includes an upper actuator casing 106 and a lower actuator casing 108.
  • the actuator casings 106 and 108 contain diaphragm plates 110 and 112, which hold a diaphragm 114 in operative engagement with a valve stem 116.
  • the diaphragm 114 is also captured between the casings 106 and 108 as depicted in FIG. 1 .
  • the lower actuator casing 108 is attached to a valve body 118 having an inlet 120 and an outlet 122.
  • a seat ring 124 is mounted in the valve body 118 and defines an orifice 126 through which fluid may flow from the inlet 120 to the outlet 122.
  • a valve plug 128 attached to an end of the stem 116 includes a sealing ring 130, which may be made of an elastomeric material, that is to sealingly engage a sealing surface 132 of the seat ring 124 when the stem 116 and the plug 128 are driven toward the orifice 126.
  • movements of the valve plug 128 and, thus, the sealing ring 130 toward the orifice 126 (e.g., toward or into contact with the sealing surface 132) or away from the orifice 126 (e.g., away or out of contact with the sealing surface 132) are caused by pressure differences across the diaphragm 114. where the pressure differences are proportional to a difference between an actual pressure at the outlet 122 and a desired pressure at the outlet 122.
  • Spacers or pins 134 are coupled to the lower actuator casing 108 and, as can be seen most clearly in FIG. 1A .
  • an end 136 of the pin 134 contacts a shoulder 138 of the seat ring 124 to hold the seat ring 124 in position within the valve body 118 in a manner that sufficiently displaces an o-ring 140 to effect a seal between the seat ring 124 and the valve body 118.
  • a plurality of such pins 134 may be spaced circumferentially about the seat ring 124 to hold the seat ring 124 in solid contact with the valve body 118 and to provide a substantially uniform sealing force to the o-ring 140.
  • FIG. 2 depicts an example two-piece trim assembly 200 for use in fluid regulators.
  • the two-piece trim assembly 200 includes a cage 202 and seat ring 204.
  • the cage 202 may be removably coupled to the seat ring 204 to facilitate interchangeability of cages and seat rings and, thus, different combinations of cages and seat rings.
  • any of the example cages described herein, such as cages 202,600 ( FIG. 6 ), and 700 ( FIG. 7 ) may be combined with any of the seat rings described herein, such as seat rings 204, 800 ( FIG. 8 ), and 900 ( FIG. 9 ), to achieve a desired flow and/or other performance characteristic for a fluid regulator.
  • example cages and seat rings described herein can be removably coupled, field servicing these components (e.g., to change a flow or other performance characteristic of a fluid regulator, to repair one or more of these components, etc.) is simplified, particularly in vertical applications in which multiple trim components are stacked and would tend to fall out of the fluid regulator during servicing operations.
  • FIG. 3 is an enlarged cross-sectional view of the example two-piece trim assembly 200 shown in FIG. 2
  • FIG. 4 is an enlarged cross-sectional view of the example seat ring 204 shown in FIGS. 2 and 3 .
  • the example seat ring 204 defines an orifice 300 through which fluid from a regulator inlet may pass to a regulator outlet.
  • the seat ring 204 includes a first shoulder 302 to receive an end 304 of the cage 202 and to align the cage 202 with the orifice 300 and the regulator body (e.g., as shown in FIG. 5 ).
  • the seat ring 204 includes a second shoulder 306 between the first shoulder 302 and a sealing surface 308 of the seat ring 204 adjacent to the fluid orifice 300.
  • the first and second shoulders 302 and 306 are spaced along a longitudinal axis 310 of the seat ring 204. More specifically, in the example of FIGS. 3 and 4 , the second shoulder 306 is spaced apart from the first shoulder 302 by a step or circumferential wall 312.
  • the step or wall 312 is configured to facilitate the alignment and removable coupling of the cage 202 to the seat ring 204.
  • an inner wall 314 of the cage 202 may be dimensioned or otherwise configured to be in close proximity to or to abut the step or wall 312.
  • the step or wall 312 and the inner wall 314 may be dimensioned to or have shapes or geometries that result in an interference fit or press-fit between the inner wall 314 of the cage 202 and the step or wall 312.
  • Such an interference or press-fit can be achieved by, for example, manufacturing the cage 202 so that at least a portion of the cage 202 is non-circular, out-of-round, etc.
  • the cage 202 can be coupled to (e.g., pressed onto) the seat ring 202 so that at least a portion of the inner wall 314 is firmly engaged against the step or wall 312 and the end 304 of the seat ring 202 is engaged with or otherwise coupled to the shoulder 302.
  • both the cage 202 and seat ring 204 can be manufactured to have similar or identical non-circular (e.g., slightly elliptical) shapes so that the cage 202 can initially be loosely engaged with the seat ring 204 (e.g., the end 304 of the cage 202 can be placed on the shoulder 302 without having to forcibly press the cage 202 onto the seat ring 204) when the non-circular shapes of the cage 202 and seat ring 204 are aligned.
  • the cage 202 and the seat ring 204 can then be rotated relative to each other, thereby causing at least a portion of the inner wall 314 to form an interference fit (e.g., bind) against the wall 312.
  • the cage 202 and seat ring 204 can be separated by rotating the cage 202 and seat 204 to eliminate the interference or binding between the step or wall 312 and the inner wall 314 and pulling the cage 202 away from the seat ring 204.
  • the step or wall 312 may be substantially circular or cylindrical and have a first diameter
  • the inner wall 314 may also be substantially circular or cylindrical and have a second diameter smaller than the first diameter to enable a press-fit engagement between the cage 202 and the seat ring 204.
  • Either or both of the inner wall 314 and the step or wall 312 may include a lead-in feature such as a chamfer, radius, etc.
  • the seat ring 204 also has a beveled surface 316 to sealingly engage an o-ring (e.g., the o-ring 504 of FIG. 5A ) against a valve body (e.g., the valve body 118) to prevent fluid from leaking between the seat ring 204 and the valve body.
  • an o-ring e.g., the o-ring 504 of FIG. 5A
  • a valve body e.g., the valve body 118
  • Still other types of engagement configurations may be employed in combination with the above-described interference and/or press-fit arrangements to removably couple the cage 202 to the seat ring 204.
  • an adhesive or a grease may be used to removably couple the cage 202 to the seat ring 204.
  • the cage 202 and the seat ring 204 may be sized to be relatively loosely coupled (e.g., without any interference or press-fit) and adhesive or grease may be applied to the shoulder 302, the wall 312, the end 304 of the cage 202, and/or the inner wall 314.
  • the adhesive or grease forms a layer between the mating surfaces of the cage 202 and the seat ring 204 that removably holds the cage 202 to the seat ring 204.
  • the inner wall 314 and the step or wall 312 may be threaded to enable the cage 202 to be threadingly engaged to the seat ring 302.
  • the cage 202 and the seat ring 204 may be removably coupled using one or more set screws and/or roll pins.
  • FIG. 5 is a cross sectional view of an example fluid regulator 500 incorporating the example two-piece trim described herein, and FIG. 5A is an enlarged cross-sectional view of a portion of the known fluid regulator 500 shown in FIG. 5 .
  • Many of the components of the fluid regulator 500 of FIG. 5 are similar or identical to those of the known fluid regulator 100 of FIG. 1 and those components are identified in FIG. 5 using the same reference numbers used in FIG. 1 . Further, the description of those components of FIG. 5 that are similar or identical to those of FIG. 1 is not repeated and the interested reader may refer to the description of FIG. 1 for those components.
  • the seat ring 204 has a beveled surface 502 that sealingly engages an o-ring 504 against the valve body 118 to prevent fluid from leaking between the seat ring 204 and the valve body 118.
  • FIG. 6 depicts an example sound suppressing cage 600 that may be used to implement the two-piece trim described herein.
  • the example sound suppressing cage 600 may be used instead of the cage 202 to reduce the noise generated by fluid flowing through the example fluid valve 500 of FIG. 5 .
  • FIG. 7 depicts an example characterized cage 700 that may be used instead of the cage 202 to achieve a different flow characteristic (e.g., a different pressure drop versus flow characteristic) than that provided by the cage 202 ( FIG. 2 ).
  • FIG. 8 depicts an example restricted seat 800 that may be used to implement the two-piece trim described herein.
  • the example restricted seat 800 may be used instead of the seat ring 204 ( FIG. 2 ) to provide a fluid orifice having a higher restriction (i.e., a greater pressure drop at any given fluid flow rate).
  • FIG. 9 depicts an example strainer seat 900 that may be used instead of the seat ring 204 ( FIG. 2 ).
  • each of the seat rings 204, 800, and 900 provides first and second shoulders and a step or wall to facilitate alignment and removable coupling between any one of the seat rings 204, 800, and 900 to of any one of the cages 202, 600, and 700.
